Thanks much for your reply, I think this is what the solution I need. But
there are two things which I am not able get. I am new to ansible, kindly
answer those question even though it was silly. whether the variables which
are being used in setfact need to be set before using that in setfact, if
so how to do that. And the 2nd question is
- set_fact:
my_env: "{{ envs|default({}) | combine( { item.split('=')[0]:
item.split('=')[1] } ) }}"
loop: "{{ dotenv_pairs.split() }}"
in the above task what is envs and what is the roll of envs|default({})
